The cottage seemed to be sealed well and bug-free, which is great for a jungly area like this. It had a bit of a musty smell but nothing terrible. It was very basic but cute and charming.
This cottage is in a very convenient location, right in the town of Volcano, which is just a mile or so from Hawaii Volcano National Park, where a lot of people go to see the volcano glow after sunset. So the location is wonderful. There are even several excellent restaurants right in Volcano - if you like Thai food, Thai Thai Restaurant is absolutely outstanding. And in general, the jungly setting around the house is very lush and beautiful.
Our main gripe was that the sheets didn't seem to have been changed. I flipped the pillowcases over and found eyelashes - only on the underside of the pillows. And I pulled the topsheet back and could see a clear impression/wrinkles where one person slept on the left side of the bed, but not the other. This wasn't a huge deal as there is a pantry with plenty of extra sheets and pillowcases, but it was a hassle to change them.
If you book through hotels.com, be sure to call the property manager beforehand (during business hours) to get instructions on how to get in (~keycode). We didn't think about this and called rather late, about 9pm, and they did answer and were very nice and gave us the code.
